"Grab a razor blade and draw a bath. I doubt anyone will miss you," Adam Richman wrote to a critic on social media

The Travel Channel has announced it will indefinitely postpone a new show featuring host Adam Richman, star of the Travel Channel’s Man v. Food, after the TV personality made some insensitive comments about dieting in an Instagram post.

Last month, Richman posted a picture of himself on Instagram showing off his new body. The TV host—who has made a name for himself taking massive food challenges like eating a yard-long bratwurst or 72-ounce steaks—dropped 70 pounds over the course of 2013 (and more since). “Had ordered this suit from a Saville Row tailor over a year ago. Think I’m gonna need to take it in a little,” he wrote in the Instagram post, adding the hashtag #thinspiration.

The backlash to Richman’s comments was swift: many were offended by a celebrity’s use of #thispiration and ridiculed him. The TV host defended himself, writing,:

Maybe you’ll acknowledge that just because someone is on TV, they are no less worthy of human kindness, respect, forgiveness or patience…Give me a [expletive] break. If anyone acts like a [four letter word] I’ll call them one. It’s not misogyny, it’s calling a spade a spade….if my use of the hashtag offended you, it was unintentional & for that I’m sorry.

But he didn’t stop there. After another wave of negative comments, Richman wrote to one of his critics: “Grab a razor blade and draw a bath. I doubt anyone will miss you.” The exchange has been captured by screen grabs on XOJane.

Richman later tweeted an apology, which has since been deleted. “Yes. I’ve responded to internet hate recently with vile words directed at those hating me. I am sorry, I should know better & will do better,” he tweeted, according to screen grabs captured by Jezebel. He followed with another (now deleted) tweet: “In real life, if you say stuff you regret in anger, you cool down, apologize & move on.If you’re a celeb on social media – it becomes a blog.” Richman claimed on Instagram that he did not know the history of #thinspiration.

Richman released yet another mea culpa on Good Morning America Tuesday morning, saying: “I’ve long struggled with my body image and have worked very hard to achieve a healthy weight. I’m incredibly sorry to everyone I’ve hurt.”

Following the controversy, the Travel Channel has postponed Richman’s new show Man Finds Food, which was supposed to premiered on July 2. The channel has yet to announce a new date for the show.
